This is a low cost and efficient circuit and can be used at homes. Note that lighting one LED in this circuit uses just as much power as multiple LEDs in series. This is different from a series circuit, where if one LED goes out, all the other ones will go out, too. Series circuits.
We already know that the capacitor is going to charge up in about 5 seconds.
It is based on the principle of driving LEDs using the clock pulses.
Can you try to create something that uses all four colors of LEDs? LED in a series circuit.
Series circuits are sometimes referred to as current-coupled or daisy chain-coupled.The current in a series circuit goes through every component in the circuit. 230V LED Driver: Here we design a simple circuit driving a series of LED from 230V AC. Sneak a peek at figure 1. LEDs in parallel (as originally shown in the recipe) require separate resistors for each, even if the LEDs are the same kind.
A series circuit has only one path in …
Therefore, all of the components in a series connection carry the same current. Hint: Use your second battery and a second set of copper tape to power the blue LEDs separately from the red, green, and yellow LEDs. Often multiple LEDs are connected to a single voltage source with a series connection.

For Further Exploration . You probably know that as long as the battery doesn’t die the LED lights up.
This is accomplished using a capacitor based power supply. For our comparison of series vs parallel circuits, let’s start by talking about the simplest circuit of all — the series circuit. Because the current through all LEDs in series is equal, they should be of the same type. Suppose there are 3 LEDs in series then this value becomes 3 x 3.3 = 9.9 . For the proof, start with our original circuit of one 10kΩ resistor and one 100µF capacitor in series, as hooked up in the first diagram for this experiment. When a series LED connection is in question, you will just need to replace the "LED forward voltage" with "total forward voltage" in the formula, by multiplying FV of each LED by the total number of LEDs in the series. Here we have a series circuit with a battery, an LED and a resistor. LEDs in series (like above) can share one resistor for the chain. A combination of these — a series-parallel circuit — has one resistor per string. Now add a second capacitor in parallel. 3X3X3 LED Cube: This is a simple a simple LED cube circuit designed without using microcontroller. In this way multiple resistors can share the same current. Sir is this circuit suitable for 9 watt and 12 watt As I want to use 9 parallel led of 1.2 watt and want to operate circuit at for 12 volt battery source led spec is 9- 10 Voff and 120 MA current please tell me what change is exaxtky required and Lm 338 required heat sink or suggest any other good ckt for different combination like strings of 4 led 3 volt Voff and 3 parallel series of this
